My config is this way:

boot-start-marker

boot system flash bootflash:isr4300-universalk9.03.16.04b.S.155-3.S4b-ext.SPA.bin
boot-end-marker

Any idea?

Hello,

the syntax looks ok actually. Can you try and upgrade the ROMMON (latest release is isr4200_4300_rommon_169_1r_SPA.pkg) ?

Yes, upgrade the ROMMON and if that does not help too, try downloading the image again.It could be a copy issue.

[Leo Laohoo]

Upgrade the ROMmon first.

Although the image was copied and verified but I decided to use a different and a little older image:

isr4300-universalk9.16.06.03.SPA.bin

And it was installed and is working properly

Now I'm going to retry installing the first one and will keep everyone informed

Thanks

Now the newer IOS-XE is also loaded flawlessly.
The first one had updated ROMMON and so ...
I just can't figure out why the new IOS didn't attempt to upgrade the ROMMON (just like the a-little-older-version IOS did)

Thank you   mhdganji110         I had the same problem    going from 3.16.04  (new box from cisco) to 16.6.4

troubleshot it almost the same way

With your suggestion  I loaded 16.3.7 with no problem, and after the reboot loaded 16.6.4
